asySapProtocolId

Module: CXAsync-MIB

OID (symbolic): CXAsync-MIB::asySapProtocolId

OID (numeric): 1.3.6.1.4.1.495.2.1.6.30.20.1.27

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-write

Description: Defines the protocol format that is used for incoming call or call request packets to the X.25 call data field.

The field consists of 4 hexadecimal octets where the first octet is coded as follows:

bits 8 & 7

- 00 for CCITT use - 01 for national use - 10 reserved for international user bodies - 11 for DTE-DTE use

When bits 8 & 7 are equal to 00, bits 6 to 1 will be equal to 000001. The first octet is shown as 01, 00, 00, 00. The first 0 in each number is optional and may be shown as 1, 0, 0, 0.

All bits of octets 2, 3 and 4 are set to 0. They are reserved as a future mechanism for providing the called PAD or packet mode DTE (user) with additional information pertaining to the calling party.

Default Value: 01,00,00,00

Configuration Changed: Operative

What is asySapProtocolId?

This read-write 4-octet hex string (default 01,00,00,00) sets the protocol identifier placed in the call/call-request user data field per CCITT X.28/X.29, used by the remote end to recognize which higher-layer protocol is riding over the X.25 call.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.30.20.1.27
snmpwalk -v2c -c public <target> CXAsync-MIB::asySapProtocolId

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.30.20.1.27.1
snmpget -v2c -c public <target> CXAsync-MIB::asySapProtocolId.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.495.2.1.6.30.20.1.27.1 s <value>
